What about Greek style yogurt, fruit and nuts/seeds for breakfast if you don't like eggs? Way better than toast or pastries and just as quick/easy. You can make 2/3 portions at a time in pots to take to work if you're out early.
For daal, add veg (cauliflower, spinach or grated courgette is good) and have a bit of naan if you don't want rice. Or quinoa would be good if you like that.
You can shortcut jacket potatoes by microwaving for 5/10 minutes then blasting for another 5/10 minutes in the oven/air fryer to crisp up.
Can you batch cook soups with protein and chunky veg so it's filling and you can eat as much as you like?
I make a 'taco soup' that has chicken, beans, sweetcorn, peppers, onions, tomatoes and spices in so it's really filling, tasty and healthy.
How much cooking, childcare and cleaning etc does your DH do and what's your respective working hours? What leisure time do you both get? DO you get the same amount of down time?
